how to deal with the array size limits problem?

I built a zero arra using "I=zeros(80,80,400,400,700);"
But the commamd window said
" The requested 80x80x400x400x700 (5340.6GB array exceeds the preset maximum array size. Creating arrays larger than this limit can take a long time and cause matlab to be unresponsive. For more information, see array size limits or presets panel"
What dose it mean?And how to deal with it?

You're asking for roughly 5 terabytes of contiguous memory. To put that into some context, in 2012 the English Wikipedia had about 1.9 terabytes of multimedia files.
If your machine has enough memory to create such a large array you can uncheck the preference to limit the amount of memory / size of the array that MATLAB will try to allocate. However, allocating that large a chunk of memory is likely to take a long time and doing anything with that data may require a second large chunk of memory.
Consider if you actually need to create that huge an array. If you describe what you're trying to do we may be able to suggest an alternate approach that requires less memory (or perhaps multiple smaller chunks that take up the same total amount of space.)

Please explain in words not code what you're trying to do with this code and we may be able to offer some suggestions.
